SPECIFICATION forming part of Letters Patent No. 394,560, dated December18, 1888.

Application led June 2, 1888. Serial No.275,825. (No model.)

To all whom, t 77060;/ concern.'

Be it known that I, AMBRosE DIEFFEN- BACH, a citizen of the UnitedStates, residing at Devils Lake, in the county of Ramsey and Territoryof Dakota, have invented a new and useful Improvement inGrain-Elevators, ot which the following is a specification.

My invention relates to an improvement in grain-elevators adapted to beused in connection with tanning-mills; and it consists in the peculiarconstruction and combination of devices that will be more fully setforth hereinafter, and particularly pointed out in the claim.

In the drawings, Figure l is a perspective view of my grain-elevator,showing the same attached to a tanning-mill. Fig. 2 is a verticallongitudinal sectional view of my improved grain-elevator. Fig. 3 is atop plan view of thesame.

A represents the case of the mill,which is ot' the usual construction,and B represents the semi-cylindrical t'an-case,which is arranged on oneend of the frame A in the usual manner.

C represents the frame of the elevator,which comprises a pair of sidebeams or boards, D, and a pair of cross-bars, E,which connect said beamsor boards near the ends thereof. Journaled between the lower ends ot'the said beams or boards is a roller, F; and G represents a similarroller, which is journaled between the upper ends of said boardsorbeams. The spindle at one end of said roller G is eX- tended beyondone side of the elevator-frame, and to the said spindle is rigidlysecured a pulley, H.

I represents an endless elevator-belt, which passes over the rollers FG, and is provided with a series of cross cleats or iiights, K, each ofwhich is made of a single piece ot' angleiron, having one side securedto the outer side of the endless belt or apron and the other sideprojecting at right angles from said apron. The said cleats or 'ightsare secured at a suitable distance apart.

To the outer end ot' the elevator-frame is secured a trough or spout, L,which is of the form here shown, is stamped orbent from a single pieceof sheet or plate metal, and has a hopper, M, at its lower end, to whichhopper the mouth ofa bag or sack is adapted to be at: tached. A pair ot'supporting-legs, M', have their upper ends pivoted to the outer end ofthe elevator-frame, and are thereby adapted to be folded against thesides ot` the 'frame when not in use.

The elevator-trame has its lower end secured to the frame A at a pointbelow the fan-case by means ot' metallic straps N, and saidelevator-frame is also secured to the fan-case by means ot similarmetallic straps, O, the elevator-traine being supported in an inclinedposition by the legs M.

P represents an endless belt, which connects the pulley ll with a pulleyon the end of the fan-shaft, whereby the rotation ot' the said fan willbe communicated to the upper roller, G, and thereby cause the endlessbelt or elevator to move in the direction indicated by the arrows inFig. 2, and consequently carry the grain which is discharged from thetanning-mill to the sack or bag.

Having thus described my invention, I Claim- The combination ot' theframe I), the rollers F G at the inner and outer ends thereof, thelatter having the pulley H, the endless apron connecting the rollers,the transverse cleats or iiights K, made ot' angle metal, and eachhaving one side secured to the apron and the other side arranged atright angles thereto, the straps N t), connecting the inner end of theframe to the mill-case, the dischargespout L at the outer end of theframe, and having the hopper M, and the belt connecting the pulley H tothe pulley on the fan-shaft, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

AMBROSE DIEFFENBACH.
